Undulatus fibratus?

[Pamela Arias]

I photographed these clouds from my bedroom window during the pandemic. They have an undulatus shape but with fibers. How would you classify them? Cirrus undulatus fibratus?

Hello Pamela, Nice patterns! I’ll give it a try.
To me it looks looks like cirrocumulus undulatus. The larger fibers in the middle are a progression of the wave pattern bottom right. All perfectly aligned. So no fibratus. Fibratus has its streaks in the direction of the wind while undulatus shows its waves perpendicular to the winds.
I hope you like it.
